"...how to store downloaded hi-rez digital... "
I believe almost no one actually addressed your question but rather described how they use computer audio.
I am not the expert and, thus, don;t want to give any advice but hi-res download is mostly in 24/96, 24/176 and 24/192 formats. I don't believe that Logitech can handle last two as well as iTune and many other suggested software and hardware solutions.
In your shoes, I would consider (and discuss with expert):
============================================
1 - labtop with minimum OP and run it on battary when listening to music - exactly as suggested above.
2 - Downoald music managment software capable to deal with hi-rez and lossless downloads and probably classic music library (a bit more compex then rock, I believe)
3A -Use Asycronius USB/S/PDIF 24/192 device connected to
3B - your DAC with regular S/PDIF input or
4 - DAC with Asycronius USB 24/192 input
Still, Buyer Beware !
